Benefits of technology

The present invention relates to a wall material used in building structures that has high water resistance. The wall material has two layers of resin film positioned on the edges and extension surfaces of the wall material. When the wall materials are spliced together, the resin films fill the gaps between the edges and surfaces, preventing water from infiltrating the interior of the building. This results in a strong barrier against water and high water resistance in the building structure.

Problems solved by technology

For example, water may cause discoloration and peeling of a coating on a surface of a wall material and may also cause generation of cracks and progress of neutralization in an internal texture that constitutes the wall material.
In addition, depending on a temperature difference in environment, the action of repeated freezing and melting of water, that is, a freezing-melting action may accelerate local destruction of the wall material and the aforementioned peeling of the coating, and may deteriorate the wall material.

first embodiment

[0044]FIG. 1 is a sectional view of a wall material X according to the present invention. The wall material X is a construction plate material for constituting an exterior wall of a building. To build an exterior wall, a plurality sheets of the wall materials X are fastened while being spliced together in the up-down direction (vertical direction) and the left-right direction (lateral direction), via a fastener to a predetermined support material included in a building frame.

[0045]The wall material X has a front surface F1 and a rear surface F2 opposite to the front surface F1. A design surface is formed on the front surface F1. The design surface has, for example, a rectangular shape (not illustrated) in front view. The outline shape of the design surface is defined by a pair of end edges extending in a first direction D1 indicated in FIG. 1 and a pair of end edges extending in a second direction intersecting the first direction D1. The dimension of such a design surface in the fir...

second embodiment

[0065]FIG. 2 and FIG. 3 each illustrate a wall-material building structure Y according to the present invention. FIG. 2 illustrates a partial vertical section of the wall-material building structure Y. FIG. 3 illustrates a partial vertical section of the wall-material building structure Y at a different part. FIG. 2 and FIG. 3 illustrate such that the above-described first direction Dl1 is oriented in the vertical direction.

[0066]The wall-material building structure Y includes a support material 40, a fastener 50, and a plurality of the wall materials X described above.

[0067]The support material 40 is a support material included in a building frame and is, for example, a furring strip. In the present embodiment, a vertical furring strip extending in the vertical direction is presented as an example of the support material 40. In the wall-material building structure Y, a plurality of the support materials 40 are disposed at predetermined intervals in the lateral direction.

Abstract

[Object] To provide a wall material and a wall-material building structure that are suitable for achieving high water resistance in the wall-material building structure.[Solution] A wall material X of the present invention has a surface-side joint portion 10 and a rear-side joint portion 20. A first resin film 31 is provided on at least one of an end surface 11a of the surface-side joint portion 10 and an end surface 21 of the rear-side joint portion 20. A second resin film 32 is provided on at least one of an extension surface 11b and an extension surface 22b. At a splice part where the surface-side joint portion 10 of one wall material X and the rear-side joint portion 20 of another wall material X are spliced together in a first direction D1, the end surfaces 11a and 21 and the first resin film 31 are disposed such that the end surfaces 11a and 21 face each other while a gap between the end surfaces 11a and 21 is filled with at least the first resin film 31, and the extension surfaces 11b and 22b and the second resin film 32 are disposed such that the extension surfaces 11b and 22b face each other while a gap between the extension surfaces 11b and 22b is filled with at least the second resin film 32. A wall-material building structure Y of the present invention is formed by using such a wall material X.

Description

TECHNICAL FIELD[0001]The present invention relates to a wall material and a wall-material building structure.[0002]A plurality of wall materials may be spliced together vertically and horizontally to thereby form an exterior wall of a building. A ceramic wall material formed in a plate shape with cement and fiber as main raw materials is known as a wall material for exterior walls. Ceramic wall materials are easily manufactured in a wide variety of patterns and colors, and are widely used as wall materials for exterior walls.[0003]Wall materials such as ceramic wall materials that constitute exterior walls are exposed to ultraviolet, carbon dioxide, water due to rainfall, and the like under an exterior environment. In recent years, the influence of water on wall materials such as ceramic wall materials has been revealed. For example, water may cause discoloration and peeling of a coating on a surface of a wall material and may also cause generation of cracks and progress of neutrali...
